If the vehicle is in cruise control
and the Electronic Stability
Program (ESP) becomes active,
the cruise control automatically
disengages. SeeElectronic
Stability Program on page 8-19.
When road conditions allow the
cruise control can be used again.
Resuming a Set Speed
If the cruise control is set at a
desired speed and then the brakes
are applied or the
OQbutton
is pressed once, the cruise control
shuts off.
Once the vehicle speed is
21 mph (33 km/h) (V6 engines)
or 24 mph (38 km/h) (V8 engines) or
greater, turn the band briey to
RES+ position. The vehicle returns
to the previously set speed and
stays there.Increasing Speed While Using
Cruise Control
There are two ways to go to a
higher speed:
Turn theIband up to the
RES+ position. Hold it there until
the desired speed is reached,
then release it.
To increase the vehicle speed in
very small amounts, turn the
band to RES+ briey and then
release it. Each time this is done,
the vehicle goes about 1 mph
(1.6 km/h) faster.
Reducing Speed While Using
Cruise Control
There are two ways to reduce the
vehicle speed while using cruise
control:
Turn theIband down to the
SET−position. Hold it there
until the lower speed desired is
reached, then release it.
To slow down in very small
amounts, turn the band to SET−
briey and then release it.
Each time this is done, the
vehicle will go about 1 mph
(1.6 km/h) slower.
Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to
increase the vehicle speed.
When you take your foot off the
pedal, the vehicle slows down to
the cruise control speed set earlier.
Using Cruise Control on Hills
How well the cruise control works
on hills depends upon the vehicle
speed, load, and the steepness of
the hills.
When going up steep hills,
you might have to step on the
accelerator pedal to maintain the
vehicle speed.
4-6 Instruments and Controls

When going downhill, you might
have to brake or shift to a lower gear
to keep the vehicle speed down.
When the brakes are applied
the cruise control is turned off.
Ending Cruise Control
Step lightly on the brake pedal.
When the cruise control is
deactivated, the CRUISE
INACTIVE message appears in
the instrument panel cluster.
Press theOQbutton at the
end of the lever two times.
Erasing Speed Memory
The cruise control set speed memory
is erased when the cruise control or
the ignition is turned off.
Turn and Lane-Change
Signals
An arrowGon the instrument
panel cluster ashes in the direction
of the turn or lane change.
To signal a turn, move the lever all
the way up or down.
To signal a lane change, slightly
raise or lower the lever until the
arrow starts to ash and release
the lever. The turn signal ashes
automatically three times.
The lever returns to its starting
position when it is released.
To cancel the lane change, move the
lever back to the starting position.
Headlamp High/
Low-Beam Changer
The headlamps must be on for this
feature to work.
Push the turn signal lever away
from you to turn the high beams on.
The fog lamps turn off automatically
when high beam is selected.
This instrument panel cluster light
3comes on while the high
beam headlamps are on.
Pull the lever towards you to return
to low beams.
To ash the high beams, pull the
lever towards you. The lamps
remain on high beam as long as
the lever is held.

Charging System Light
This light will come on briey when
you turn on the ignition, and the
engine is not running, as a check to
show it is working. Then it should
go out when the engine is started.If the light comes on and an
Alternator message on the Driver
Information Center (DIC) stays
on, you may have a problem with
the electrical charging system.
Have it checked by your
dealer/retailer.

Brake System Warning
Light
Your vehicle’s hydraulic brake
system is divided into two parts.
If one part is not working, the other
part can still work and stop you.
For good braking, though, you need
both parts working well.
If the warning light comes on, there
is a brake problem. Have your
brake system inspected right away.
If your vehicle has anti-lock brakes,
this light should come on when
you turn the key to START. If it does
not come on, have it xed so it
will be ready to warn you if there is
a problem.

but the regular brake system
warning light is not on, the antilock
brakes are not working properly,
but the regular brakes are still
functioning. Have your vehicle
serviced right away. If both brake
lights are on, you do not have
antilock brakes, and there’s a
problem with your regular brakes as
well. Have your vehicle towed for
service. SeeTowing Your Vehicle
on page 9-88.

not be covered by the vehicle
warranty. Shift to R (Reverse)
only after the vehicle is stopped.
R (Reverse):Use this gear to
back up.
At low vehicle speeds, R (Reverse)
can also be used to rock the vehicle
back and forth to get out of snow, ice,
or sand without damaging the
transmission. SeeIf Your Vehicle is
Stuck in Sand, Mud, Ice, or Snow on
page 8-29for additional information.N (Neutral):In this position, the
engine does not connect with
the wheels. To restart the engine
when the vehicle is already moving,
use N (Neutral) only.
{CAUTION
Shifting into a drive gear while the
engine is running at high speed is
dangerous. Unless your foot is
rmly on the brake pedal, the
vehicle could move very rapidly.
You could lose control and hit
people or objects. Do not shift into
a drive gear while the engine is
running at high speed.
Notice:Shifting out of P (Park)
or N (Neutral) with the engine
running at high speed may
damage the transmission. The
repairs would not be covered by
the vehicle warranty. Be sure
the engine is not running at high
speed when shifting the vehicle.D (Drive):This position is for normal
driving. It provides the best fuel
economy. If more power is needed
for passing, and the vehicle is:
Going less than 35 mph
(55 km/h), push the accelerator
pedal about halfway down.
Going about 35 mph (55 km/h) or
more, push the accelerator all the
way down.
Downshifting the transmission in
slippery road conditions could result
in skidding, see Skidding under
Loss of Control on page 8-23
Notice:Spinning the tires or
holding the vehicle in one place
on a hill using only the
accelerator pedal may damage
the transmission. If you are stuck,
do not spin the tires. When
stopping on a hill, use the brakes
to hold the vehicle in place.
Driving and Operating 8-7

Alcohol affects four things that
anyone needs to drive a vehicle:
judgment, muscular coordination,
vision, and attentiveness.
Police records show that
almost 40 percent of all motor
vehicle-related deaths involve
alcohol. In most cases, these deaths
are the result of someone who
was drinking and driving. In recent
years, more than 17,000 annual
motor vehicle-related deaths have
been associated with the use of
alcohol, with about 250,000 people
injured.
For persons under 21, it is against
the law in every U.S. state to drink
alcohol. There are good medical,
psychological, and developmental
reasons for these laws.
The obvious way to eliminate the
leading highway safety problem
is for people never to drink alcohol
and then drive.Medical research shows that alcohol
in a person’s system can make crash
injuries worse, especially injuries to
the brain, spinal cord, or heart.
This means that when anyone who
has been drinking — driver or
passenger — is in a crash, that
person’s chance of being killed or
permanently disabled is higher than
if the person had not been drinking.
Control of a Vehicle
The following three systems help
to control your vehicle while
driving — brakes, steering, and
accelerator. At times, as when
driving on snow or ice, it is easy to
ask more of those control systems
than the tires and road can provide.
Meaning, you can lose control of
your vehicle.
Adding non-dealer/non-retailer
accessories can affect your vehicle’s
performance. SeeAccessories
and Modifications on page 9-3.
Braking
SeeBrake System Warning Light on
page 4-15.
Braking action involves perception
time and reaction time. First,
you have to decide to push on the
brake pedal. That is perception time.
Then you have to bring up your
foot and do it. That is reaction time.
Average reaction time is about
three-fourths of a second. But that
is only an average. It might be
less with one driver and as long as
two or three seconds or more
with another. Age, physical
condition, alertness, coordination,
and eyesight all play a part. So
do alcohol, drugs, and frustration.
But even in three-fourths of a
second, a vehicle moving at 60 mph
(100 km/h) travels 66 feet (20 m).
That could be a lot of distance in an
emergency, so keeping enough
space between your vehicle
and others is important.
Driving and Operating 8-17

And, of course, actual stopping
distances vary greatly with the
surface of the road, whether it is
pavement or gravel; the condition of
the road, whether it is wet, dry, or icy;
tire tread; the condition of the brakes;
the weight of the vehicle; and the
amount of brake force applied.
Avoid needless heavy
braking. Some people drive in
spurts — heavy acceleration
followed by heavy braking — rather
than keeping pace with traffic.
This is a mistake. The brakes might
not have time to cool between
hard stops. The brakes will wear out
much faster if you do a lot of
heavy braking. If you keep pace
with the traffic and allow realistic
following distances, you will
eliminate a lot of unnecessary
braking. That means better braking
and longer brake life.
If your vehicle’s engine ever stops
while you are driving, brake normally
but do not pump the brakes. If you
do, the pedal could get harder topush down. If the engine stops, you
will still have some power brake
assist. But you will use it when you
brake. Once the power assist is used
up, it can take longer to stop and the
brake pedal will be harder to push.
Adding non-dealer/non-retailer
accessories can affect your vehicle’s
performance. SeeAccessories
and Modifications on page 9-3.
Antilock Brake
System (ABS)
Your vehicle has the Antilock Brake
System (ABS), an advanced
electronic braking system that will
help prevent a braking skid.
When you start the engine and
begin to drive away, ABS will check
itself. You might hear a momentary
motor or clicking noise while this
test is going on, and you might even
notice that the brake pedal moves
a little. This is normal.If there is a problem with ABS, this
warning light will stay on. See
Antilock Brake System (ABS)
Warning Light on page 4-16.
Let us say the road is wet and you
are driving safely. Suddenly, an
animal jumps out in front of you.
You slam on the brakes and continue
braking. Here is what happens
with ABS:
A computer senses that the wheels
are slowing down. If one of the
wheels is about to stop rolling, the
computer will separately work
the brakes at each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
you steer around the obstacle while
braking hard.
8-18 Driving and Operating

As you brake, the computer keeps
receiving updates on wheel speed
and controls braking pressure
accordingly.
Remember: ABS does not change
the time you need to get your
foot up to the brake pedal or always
decrease stopping distance. If
you get too close to the vehicle in
front of you, you will not have time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room up ahead
to stop, even though you have ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down rmly and
let antilock work for you. You might
hear the antilock pump or motor
operate, and feel the brake
pedal pulsate, but this is normal.
Braking in Emergencies
With ABS, you can steer and
brake at the same time. In many
emergencies, steering can help
you more than even the very best
braking.
Electronic Stability
Program
The vehicle has the Electronic
Stability Program (ESP®) that assists
with directional control of the vehicle
in difficult driving conditions by
reducing engine power and applying
the brakes to individual wheels. This
is especially useful in slippery road
conditions. The system operates if it
senses that the rear wheels are
spinning too much, are beginning to
lose traction or if it senses that the
vehicle is not moving in its intended
direction. It turns on automatically
every time the vehicle is started.When ESP is working, this light
and the STABILITY CONTROL
ASSISTANCE message will come on
and the ESP CTRL message will be
displayed at the bottom of the DIC.
The STABILITY CONTROL
ASSISTANCE message will remain
on while the system is working
until the
3button is pressed to
display the trip computer. The
ESP CTRL message stays on at the
bottom of the DIC while the
system is working.
Driving and Operating 8-19

When this light and the STABILITY
CTRL OFF message is on briey and
the ESP OFF message is displayed
at the bottom of the DIC, the system
will not limit wheel spin.
If the ESP OFF message is always
displayed at the bottom of the
DIC when the button is pressed
to turn the system on or off, the
system needs repair. Contact your
dealer/retailer.The system is on when this light
and the STABILITY CTRL ON
message is displayed briey on
the DIC.
ESP Operation
ESP limits wheel spin by reducing
engine power to the wheels and
by applying brakes to each
individual wheel as necessary.
The ESP system is enabled
automatically when the vehicle
is started, and it will activate
the STABILITY CONTROL
ASSISTANCE light and the ESP
CTRL message on the DIC if it
senses that any of the wheels are
spinning or beginning to lose traction
while driving.Notice:If the wheel(s) of one axle
are allowed to spin excessively
while the ESC/TCS, ABS and
Brake warning lights and the
SERVICE ESC and/or SERVICE
TRACTION messages are
displayed, the differential could be
damaged. The repairs would not
be covered by the vehicle
warranty. Reduce engine power
and do not spin the wheel(s)
excessively while these lights and
this message are displayed.
The traction control system may
activate on dry or rough roads or
under conditions such as heavy
acceleration while turning or
abrupt upshifts/downshifts of the
transmission. When this happens,
a noise, vibration, or a reduction
in acceleration may be noticed.
This is normal.
Adding non-dealer/non-retailer
accessories can affect the vehicle’s
performance. SeeAccessories
and Modifications on page 9-3for
more information.
